Undo nut and bolt and slide cover off the main drive belt pulley houseing..left side just under foot platform above blade deck.The hard job is to tap that pully up off the shaft. Once that is done you unclip 4 clips and the blade cutting deck comes away from mower.
If it is just the main blade drive belt above deck once you slide that cover off you are there.Anything under the deck,best drop it. Good luck
